Quick Tip: Chrysler/Dodge/Jeep/Ram 3.2L and 3.6L DONT FORGET THE COIL BOOTS!

[@Coyote5555]

Nice to see a comback and more videos please... great stuff

[@MotorCityMechanic]

I finally got motivated enough to make a few. Thanks for checking this one out

[@vince7247]

Considering the work required to access the coils, a no brainer. Thank you for the tip.😊

[@MotorCityMechanic]

Most want to replace all 6 coils while in there.....usually with aftermarket which means they might be doing the same job again

[@WickWickWACK]

Naaahhhh. There's a plethora of no brainer sufferers walking around out there

[@blazeandcyrus]

David you were freaking me out talking about the part falling out of the coil while right above open intake ports lol. :)

[@MotorCityMechanic]

I always have paper towels in the ports.....I forgot to on this video. I made another video right after this one and then I remembered to do that lol. Good eye

[@blazeandcyrus]

Usually you got all the bases covered.@@MotorCityMechanic Oddly enough I'm replacing coils/ coil boots and plugs this weekend on my 3.6 this weekend. Thanks for all the great videos throughout the years.

[@promastersonly1419]

Finally! I'm glad someone said it. The coil is just a transformer, potted in wax and sealed for all time. There's nothing in there - just a lump of iron with wire wrapped around it. And, in theory, each one has 1/6th the mileage on it that the engine does. I'm a bad capitalist, but I'm happy to tell customers NOT to replace the coils unless there's an issue. And on my own fleet I replace them at 400k out of sheer guilt but not need.

[@sheerwillsurvival2064]

The real deal. No BS not a lot of fluff talking. Just tips and learning 👍🏻👊🏻

[@MotorCityMechanic]

Appreciate the feedback and support!

[@XxSxOxBxX]

You are a master at teaching! Your videos have saved me thousands of dollars and I appreciate all your videos! Thank you! I would love to see some videos on suspension components, c/v axles, etc. Specifically for 2013 Grand Caravans. I’ll be watching.

[@MotorCityMechanic]

I’ll keep it in mind for sure

[@UNVME]

Great to see ya back! Everyone always bad mouthing Chrysler products... I have a 13 Avenger RT with 228,000. At 25k it had the oil cooler leak, and about 18k had the oil preasure sensor fail. Other then that. It's had plugs changed once, coolant flushed, transmission fluid changed once, and synthetic oil every 5k. It will still burn the front tires!! It is parked now though. Needing struts, control arm bushing, all engine / trans mounts. Normal stuff with the spirited life its had. Oh and 3 condensers and 1 compressor due to rock damage.

[@MotorCityMechanic]

No brand is perfect and you have to address things as they happen before they build up to numerous things. I prefer Chrysler but there are certain engines or cars that I say dont buy

[@tdz69]

You are the MAN with these engines!!! Ty

[@antiangelofmusic]

Ive never done a tune up on a car with cop without changing the boots!

[@MotorCityMechanic]

I don’t any more either.

[@steveb319]

Glad to see you back. As always, good instructional video and advice for us DIY’ers.

[@Japplesnap]

Another great tip for us Pentastar owners. Thanks for adding value to the community!

[@scottsaathoff8124]

Great information! I wish I had known this a couple years ago. I had a boot tear in half when I was replacing rocker arms. I bought the full coil, not even knowing you could buy only the boots. I'm a full-time Uber driver and currently have a 2017 Chrysler 300C with 329,714 miles. I've replaced the rocker arms, oil cooler, 2 radiators, 2 alternators, starter, battery, PCV valve, MAP sensor, three of the four O2 sensors (with a code for the fourth one currently coming up), both front CV axles twice, right lower control arm, struts, springs and shocks, and more - and need to put in my third set of spark plugs and both inner tie rods. Your videos have been extremely helpful with several of those repairs. Thank you!

[@MotorCityMechanic]

I have seen them with over 500,000 miles as well! Every at is going to need items over time as you have seen and glad I could help in any way possible

[@jaymills3843]

Awesome TIP ! Easily over looked when diagnosing the proverbial Mis Fire

[@thearrow5793]

If course David big thumbs 👍👍👍👍👍👍👍👏👏👏👏👏👏

[@MotorCityMechanic]

Thanks!

[@eddiea3782]

Great video. Thanks David. I'm sure at some point I'm gonna have to do some service of the plugs and boots and this video is very informative. My 2013 Dodge Grand Caravan has been one of the best vehicles I've ever owned. Going on 11 years and the intake has never been off yet. Not one engine/trans issue in all these years. She's quiet and powerful still just like new.

[@EarlSinclair97]

Agreed. Always replace the PCV valve with a MOPAR unit on the P-Stars. Aftermarket units are a crapshoot.

[@86twin]

Good to know. I am going to replace mine and almost went aftermarket

[@MotorCityMechanic]

I learned that over the years…..liked the cheaper price and had great hopes but was let down. Mopar only for me from here on out

[@nimmerb]

Great to know the boot is the recommended item of the coils. Loving the Pentastar. I have already done the rockers/cam followers following your video!!! Other than that, nothing major. Hoping to go over 300k miles.

[@MotorCityMechanic]

They can have their issues but I do like them and power they have . I have seen some with over 500,000

[@arthurrodesiler3109]

Great info david Glad to see you have time for some videos. Thanks they are very helpfull.

[@MotorCityMechanic]

Had to make time and force myself to. About know why but it becomes a chore these days. I need to change that

[@fernandon1429]

You and your videos are awesome... THANK YOU!

Always much appreciated

[@mh-tn3ic]

Thanks for these info videos . I enjoy being a do it yourselfer however I tried changing the PVC valve on my jeep wrangler and after spending half a day on it I admitted defeat a took i to a shop. That thing is a bear to get to.

[@MotorCityMechanic]

It’s right for sure in that engine. I fully understand. Thanks for watching

[@kevinm5177]

Very helpful! Thanks. Also glad to see you use WYZE cameras in your shop!

[@MotorCityMechanic]

For the price you cant beat them. Thanks for watching

[@robertgreen4050]

Great info 👍 I mostly help my kids although they are grown but when it comes to cars they are clueless have tried to show them how to do some basic stuff but these young people today don't want to learn nothing

[@kirkout7366]

If only they could take a mechanical course via a game console, right?

[@cyberintel13]

Is it a good idea to use dielectric grease on the end of the boot spring making contact with the spark plug?

[@MotorCityMechanic]

Personally I never use it and haven’t had an issue. Doesn’t mean that it doesn’t have any benefits….i just haven’t seen problems when you don’t. Seems a lot of people use too much of it when they do use it.

[@Travesty_INC]

Great tip. I recently swapped a 19 classic Pentastar engine into my 2014 Ram when the stock motor went FUBARed. When I do the plugs soon I'll be doing these as well.

[@jc_from_tx9229]

Thank you for the series on this motor, I do all my own work on my Jeep and greatly appreciate this info.

[@bryanfuller21]

Great content as always and never knew you could purchase just the boots only. Thank you!

[@MotorCityMechanic]

Happy to help! I didn’t either until a few years back.

[@victornaja-paz5241]

can computer go out on this type of engine. 3.6l talking about a 2014 vw routan . i have a misfire on cyilnder one. it pass all other thest i notice the pulse width is lower on cyilinder 1 compare to the rest of the other 5 cylinders. any help would be appriciated please. misfire strickly on idle. with little gas it clears right up no misfire on load

[@MotorCityMechanic]

Most likely a rocker arm starting to go bad that isn’t making tapping sounds yet. I would inspect the 4 rockers arms for that cylinder.

[@victornaja-paz5241]

sorry how would i inspect and what am i looking for play basically ?? can i do it with out removing the rocker arms maybe just reliving the tension wild all in place?? @@MotorCityMechanic

[@VictorLuna-t1m]

Hello Dave, I love the channel and trust your advice and expertise above all other mechanics. I have looked everywhere for a procedure for replacing my power steering fluid on my 2015 Jeep Grand Cherokee with a 3.6 and V6. Can’t find anything in writing or any videos that I find to be trustworthy. Can you please make a video on this procedure? My jeep has 75k miles on it. Best, Victor

[@charlierumsfeld6626]

Thanks for this. I didn't know the boot was separate from the coil

[@mattmorrow3656]

Great video David, Thanks for the information! How about some more 4th and 5th gen 6.7 Cummins tech videos?

[@Sheldonclayton]

Thanks for the lessons.

[@MotorCityMechanic]

Your welcome and thanks for watching!

[@timothyball3144]

Ive got a customer with a bunch of Promasters and the oil coolers have been failing around 70,000 miles so I have been changing the plugs at the same time. That may be overkill, but the gap has been maybe .010 extra. How much extra gap can these plugs handle? Also, thanks for your time with these tips. Much appreciated.

[@promastersonly1419]

We work exclusively on Promasters, and take them regularly to 200k-300k on plugs. I probably wouldn't recommend that for a regular "car", which may take 8 years to log 100k. You are correct though - the electrode wears and the gap increases, and that's what takes out a plug. I couldn't give you a gap spec to go by, nor will there usually be any symptoms other than at the extreme, a misfire code.

[@shanevanorder2644]

I never new those came apart

[@MotorCityMechanic]

For the longest while I didn’t know either but most cars you can buy the coil boots separately

[@BonheurEsperer]

[@StephanWelch-o2u]

Thanks David for another great video! I would be very interested in your thoughts about the intake rocker arms with the VVL cam shafts.

On my 5.7 Grand Cherokee it has dual boot coils. Last time changed plugs one coil boot was burned. Last person to change plugs failed to tighten plugs cylinder 5

Good Tip Thanks . Question for anyone when warmed up at idle in drive I get a sporadic shudder with no code just changed spark plugs and crankshaft sensor . boots were ok anyone else had this issue ? 3.6 l

[@desertdog2282]

Thanks for the tip

[@davidrobins4025]

My plugs were replaced by Lake Huron Chrysler, Goderich, ON at 160,000 km (technically 99,419.39 mi) but I do not know if the boots were replaced. My 2013 Dodge Charger 3.6L VVT now has 198,075 km on it and is still running without hesitation 🤞. BTW, I change the oil and filter (Synthetic) at not more than 5,000 km. So far I do not hear the dreaded "tick, tick, tick." Thanks for the excellent advice

[@promastersonly1419]

Because it was a dealership, I doubt they left any of your money on the table by NOT selling you the boots.

[@HITMAN-he9ws]

how about make a video about how to change transmission filter and oil on the 3.6 engine thanks

[@MotorCityMechanic]

Which vehicle…….they used this engine in pretty much everything.

[@HITMAN-he9ws]

Grand cherokee 2016 v6 to up . Chrysler said it lifetime, no oil changing for those transmission, ZF and I think it b.s ..

[@robtoyos76]

Great tips. thanks

[@03_TK_MNE]

Sir, I've now got a small leak in my main rear seal (Engine Crankshaft Seal) as well as the need to replace BOTH Left & Right cylinder head gasket. I saw videos for the Left but do you have anything on the Right? I am seriously considering taking on these projects myself as I've already spent $6300 in repairs to my 2013 JKU since this January 2024. I'm currently quoted at $1,096.68 for the crankshaft work & $3,507 for the Cylinder head gaskets. I simply can't afford anything further so I've got to get about it on my own. Much appreciated for your videos already.

[@kirkout7366]

At idle, most times ok. But under load, misfires. 200k on 2016.sometimes, it feels like it is skipping, but doesn't rip a misfire code.

[@shugg0517]

David I have a 2012 Charger RT. The problem I'm having is putting it in drive from park. What do you suggest to start when trying to figure out the problem. It takes a minute to put it in gear after pumping the brakes and cutting the car off and restarting it. Sometimes not in that particular order.

[@rtraymond]

What do you think of adding an oil catch can?

[@MotorCityMechanic]

Personally I see no benefits overall. For me…..catch cans work great for direct injection vehicles not the 3.6L. Otherwise if the PCv valve is working correctly you won’t get excessive oil in the intake.

[@thegeekdreams]

Thanks Dave. Would recommend going OEM on spark plugs or NGK Iridium series or Denso V?

[@PhillyDee215]

😅...Just imagine if the valve train and the rest of the block was just as reliable as the block itself

[@MotorCityMechanic]

Very true. Rarely ever replace an engine but have done many repairs to everything else on it

[@PhillyDee215]

@@MotorCityMechanic they would never sell a vehicle again lol. Consumers wouldn't need one unless they just want something more modern looking

[@promastersonly1419]

I disagree. Other than the pentastar tick and oil cooler leak, both of which have been more or less resolved with the AH rockers and Dorman aluminum cooler, the engines have ZERO major pattern failures. A minor exception is the oil pump solenoid, which isn't critical to fix. But stuff they almost NEVER need? Chains, chain guides, chain tensioners, crank sensor, crank bearings or cam bearings, oil pumps, water pumps, knock sensors, throttle bodies, map sensors, phasers, crank pulleys. Even front and rear seals are crazy rare. We regularly take them out to 600k and the compression is still good enough to run. Pound for pound, probably the cheapest engine on the planet to keep running. And if you blow one up, another perfectly good one is $1800 at LKQ.

[@PhillyDee215]

@@promastersonly1419 @promastersonly1419 I do agree, working on Promasters for a while i rarely seen anything else go wrong but for Dodge and Chrysler buyers a valve train fix is not cheap for your average driver and of course it depends on what shop they take it to. Now yes they do have the revised rockers but unfortunately if u don't have the Pentastar 3rd Generation engine, that means every one else with the older engines will have to find out the hard way

[@promastersonly1419]

The rocker problem was mostly corrected for the 2019 model year, but I'm in general agreement. For me, the transmission is the weak link, not the engine. Still, because this is what I do I did quite a bit of research and found a guy who operates a fleet of Transits in basically the same way as we do. Running all the numbers, and looking over as many years we had data available, the overall cost of ownership is pretty close to identical. The Fords break in different but equally expensive ways. Your only other choice, the Sprinter, is such an overpriced piece of crap that's LESS reliable even while the fuel costs more. If you step backward to Ford E vans or Chevy vans, they are reliable but get terrible fuel economy, and ALSO have disposable transmissions. Conclusion: all machines break, the one with the least parts will break the least. Advantage Promaster, with no egr, no fuel return, no fuel filter, no MAF sensor, no TCM, no fuel pressure regulator, and a few other things. @@PhillyDee215

[@Chris_greene]

Could you help me figure out what’s up with my truck. 2017 ram 1500 with this engine, I originally had a p0301 code. So I changed the spark plug and ignition coil on cylinder one, then the check engine light came back on, but this time it was a p219a. I’ve swapped out the O2 sensor, and also did the fuel injector on cylinder 1, but p219a is for bank 1 so not just cylinder one. It’s driving me crazy….

[@kirkout7366]

Steering angle sensor replacement?

[@applecider6951]

In doing rockers/lifters 2013 gc @100k noticed 3 times as much black tar carbon on bank right side vs left side what can cause this? Pcv? What your thoughts on Seafoam to clean it out?

[@ИвоБобул-т5х]

If the boot is bad and the misfire happens it should light a check engine, shouldn't it?

[@promastersonly1419]

Yes, and it will. Although....there is a schedule. The computer logs every misfire for every cylinder, but it takes over a certain threshhold to trigger a P030x (the x being which cylinder) pending code which will NOT light the light. At some point above that, it will log enough misfires to light the light, but you won't notice any difference in driveability. At the extreme, the light will be flashing and it will feel like you are driving over rumble strips. You can often lessen this by locking into a lower gear to keep the revs up - misfires are most likely to happen at lower rpm but high load, like highway cruise. Be advised: driving around on a misfire will eventually burn out the cat on that bank of cylinders, as unburned fuel burns inside the cat.

[@samanomedina]

What if there is a 2014 model (10 years old) at the time I am writing this, but the vehicle only has done 75 thousand kilometres (about 47 thousand miles), would you still recommend to change the spark plug boots? Thanks
